معرفی
Sarah Ivory is an Associate Professor in the Department of Geosciences at Pennsylvania State University. She specializes in paleoecology, using fossil pollen records and sedimentary data to study past ecosystem changes, particularly in tropical regions. Her work integrates climate modeling, remote sensing, and field studies to understand vegetation responses to historical climate shifts, with an emphasis on informing conservation strategies in biodiversity hotspots. Key research areas include the African humid period, tropical alpine environments, and human-environment interactions in regions like Oman and Madagascar.
Her research focuses on reconstructing past climatic and ecological conditions using multi-proxy approaches, including ostracode stratigraphy, hyrax middens, and lake sediment cores. She has contributed to projects such as the Neotoma Paleoecology Database, which curates open-access paleoenvironmental data. Recent studies address topics like hydroclimatic variability in East Africa, postglacial vegetation dynamics in Pennsylvania, and the impacts of abrupt climate changes on montane forests.
Ivory collaborates on interdisciplinary initiatives, including the Earth System Science Center at Penn State, and has secured grants for projects analyzing sedimentary records in California and Africa. Her work highlights the importance of paleoenvironmental data in predicting future ecological responses to climate change, particularly in vulnerable ecosystems.
